From what Secluff has said it sounds like it is an aftermarket sunroof. Given that, I would recommend that you remove it and patch the roof. Since this is a very desirable car and appears in nice original shape it will be worth more if put back to original condition. You also don't see very many...
Answer depends on what the car is...
If this is a mostly original car then this will for sure hurt the value with a hole cut in the roof. Since this is a Q code, that makes it rarer and also more desirable.
If this is a non original or resto mod then if done correctly might not hurt and could...

Not sure if this helps but here is a pic of where remote goes on a deluxe interior...assume standard interior has the hole in same spot relative to the door.
I would NOT go with the repo...I purchased one for my 72 and could not get it to fit correctly. The width is shorter than the original and I was unable to get to mount/line up to the fenders at all. I ended up finding a NOS one and installed that and it fit perfectly. If you try to use your repo...
Here is what I would try relative to the trunk...
Remove the trunk latch and then slowly try to close your trunk lid and see if it will go down further. On one of my cars I had to elongate the holes in the trunk latch to let it slide a bit more and then was able to get trunk lid to fit better...
Congrats on the car and best of luck with the restoration. This is a very rare car. Here is a pic of my 1972 Q code convertible, all original with 84k miles. Just about nearing the end of a five year restoration.
I have used a thin putty knife like was show in post above along with lacquer thinner. It cuts the grease really well and does not have the smell of other solvents so your wife may like. For sure the worst part of the restoration.
Brett,
Here is a pic of my car with the lower body paint. Don't forget the small black stripe just above the body line. This is/was a tape line that can still be purchased. Good luck.

Here is a link to all the vacuum diagrams which should go a long ways towards helping you get it sorted out. Good luck.

I think that is the end of the door weatherstrip. That metal piece has rubber molded around it and one end of the weatherstrip has a sheet metal screw that attached to frame?
I had the same problem. Call Mustangmarket.com and they will make a pair for you without the manual window crank holes in them. They will also cut out the power window holes for a small fee.
Someone else can chime in here also but I am pretty sure that piece was NOT chrome plated as it would reflect into the drivers vision. I think it was a dull metal appearance when new.
